I have a knitting pattern that calls for the Dig stitch. Does anyone know how to do it?

Answer 1

I think it means you have to reach deep into the fabric (dig) to be sure you get all the stitches needed as in this bag:
For the bag bottom trim: You’ll be picking up stitches around the perimeter of the base, first on
the three attached sides. When you hit the open side, where the two layers of fabric were not
joined when you began knitting in the round, be sure to dig through both layers of fabric every
few stitches and catch a stitch from the reverse side; this will serve to attach the two layers of
fabric and ensure that they felt together securely.

Are you sure you don't mean digistitch? That would be a type of computer software for making patterns.
